Creating an individual brewing profile

With the 3TEMP web application, you have the freedom to experiment with your recipe parameters and find the perfect brew. Don’t worry, you can’t go wrong – we promise, the brewer won’t explode!

The recipe editor is structured into basic parameters and the three brewing phases:

  1. Pre-brew Phase
  2. Extraction Phase
  3. End Phase

The different phases come with a few factors to consider, such as temperatures, duration, and the use of pulses.

It may not seem complicated at all, and that’s because it really isn’t. However, these parameters enable you to achieve the absolute best when it comes to brewing exceptional filter coffee.

You want to delve deeper?

We kindly suggest a gradual adjustment rather than making all changes at once. By fine-tuning the parameters with each brew, you’ll notice that, apart from the coffee and basic settings, there are just six key parameters to consider. Gaining a clear understanding of these will undoubtedly bring you the joy and satisfaction you’re seeking.

Coffee parameters

Although the coffee parameters aren’t included in the brew recipe, they play a crucial role in shaping the taste:

Basic parameters

BREW RATIO (g/l)

The official SCA standard is 60g/L

While we recommend this as a starting point, remember that coffee varietals differ, so slight adjustments may be necessary for the perfect cup.

Also, please be aware that reducing the ratio can have a beneficial impact on the environment. READ MORE

WATER (ml)

You can set your preferred standard volume. The ratio will then automatically calculate the required coffee (g).

The standard Thermos for a 3TEMP brewer is a 2.5 litres thermos. In that case you can set a volume for 2500 ml.

COFFEE (g)

The required coffee grounds are automatically determined by the Brew Ratio (g/l) and Water (ml).

Adjusting the Coffee (g) parameter will, in turn, change the Water (ml).

Pre-brew phase

PRE-BREW TEMP

Taste-effects:
Character and Intensity

This parameter is linked to the roast level of the coffee: The lighter the roast, the lower the temperature you should set.

PRE-BREW VOLUME (0-15%)

Taste-effects:
Mouthfeel

When you’re using a brew ratio of 60 g/l, starting with a pre-brew volume of about 12% is a good idea (that’s a little over 2 grams of water for every 1 gram of coffee).

Also, remember that the grind size matters. If you grind the coffee beans finer, it’ll make your coffee taste richer and give you more coffee in your cup. But remember that a batch brewer needs a less fine grinded coffee than a home brewer.

PRE-BREW TIME (sec)

Taste-effects:
Sweetness and Intensity

The basic rule is: The lighter the roast, the longer the pre-brew time to allow unwanted carbon dioxide* to escape. A commonly suggested pre-brew time falls in the range of 40 to 60 seconds.

A combination of a high Pre-brew temp and an extended Pre-brew time may lead to over-extraction.


*) Allowing the release of carbon dioxide enhances coffee flavor in two ways.

  1. Initially, carbon dioxide carries a sour taste. Failing to let the coffee grounds bloom before brewing will result in this gas imparting a sour flavor to the coffee.
  2. Furthermore, carbon dioxide acts as a barrier to water, disrupting the brewing process. The full extraction of coffee’s aromatics and oils by water can only occur once carbon dioxide has dissipated.

Extraction phase

BREW TEMP 1

Taste-effects:
Extraction and Balance

In most cases, we advise:
Dark roast => 95-99°C
Light roast => 92-96°C

Brew temp 1 should be approximately 3° – 5° lower than the Pre-brew temp to avoid over extraction

BREW PULSES (ml/pulse)

Taste-effects:
Extraction and Balance

Affects the total extraction time and how evenly the coffee grounds are extracted. Check filter basket after the brew is done. Continuous flow normally works best for 800-1200ml

End phase

BREW TEMP 2

Taste-effects:
Bitterness and Balance

Less temp => lower extraction = less bitterness in the final brew phase

Brew temp 2 should be approximately. 3° – 5° lower than the Brew temp 1 to avoid bitterness

AFTER DRIP

The ‘After Drip’ parameter does not affect the taste; it solely manages the timer to ensure the thermos remains under the brewer while any post-brew dripping occurs.

Bottom controls

3TEMP - Key Factors Influencing Coffee Flavor in Filter Coffee - Basics

This is a straightforward explanation focusing on the primary factors that have the most influence. While there are more intricate connections between individual factors, we’ve opted for this image to keep things clear and easy to understand.

As you can observe, beyond the fundamental aspects of coffee, the pre-brew phase plays a substantial role in determining the coffee’s flavor.

This is one of the key factors contributing to the exceptional brewing results achieved with the 3TEMP brewers.

Key Factors Influencing Coffee Flavor in Filter Coffee

Acidity

Mainly influenced by: [ Grind Size ]

In the world of round-filter brewers like the 3TEMP machines, the golden rule often suggests the ideal coffee grounds fineness falls between 500 and 800 microns.

Keep in mind that coffee characteristics can vary between types and even among different roasters. Opting for a finer grind size will enhance the acidity, while choosing a coarser grind size will result in a brew with lower acidity.

Basic rule:

  • Finer = more acidity
  • coarser = less acidity

Aroma

Mainly influenced by: [ Grind Size ]

Smaller grind size > Larger surface area > More extraction.
However, remember that “bigger” isn’t always better. It should be just right. Finer grinding can enhance aroma but may also introduce bitterness due to longer extraction. The key is to strike the right balance.

Balance

Mainly influenced by: [ Brew temp 1 | Brew temp 2 | Pulses ]

Brew temp 1

Brew temp 2

Pulses

The pulses affect both the total extraction time and the evenness of coffee grounds extraction. We recommend checking the coffee grounds in the brew basket once the brewing process is complete.

Bitterness

Mainly influenced by: [ Brew temp 2 ]

Our recommendations:

A touch of bitterness can be an essential element in coffee flavor. However, excessive bitterness extracted during the final stages of brewing is usually undesirable. With 3TEMP brewers, you have the capability to prevent this. To avoid unwanted bitterness, set the second brewing temperature, “Brew temp 2,” about 3-5 degrees lower than Brew temp 1. This adjustment ensures a well-balanced and less bitter coffee taste.

Body

Mainly influenced by: [ Brew ratio ]

Character

Mainly influenced by: [ Pre-brew temp ]

Extraction

Mainly influenced by: [ Brew temp 1 | Pulses ]

Intensity

Mainly influenced by: [ Pre-brew temp | Pre-brew time ]

Mouthfeel

When you’re using a brew ratio of 60 g/l, starting with a pre-brew volume of about 12% is a good idea (that’s a little over 2 grams of water for every 1 gram of coffee).

Also, remember that the grind size matters. If you grind the coffee beans finer, it’ll make your coffee taste richer and give you more coffee in your cup. But remember that a batch brewer needs a less fine grinded coffee than a home brewer.
